Standard & Poor’s reports that the preliminary ratings it assigned to the MultiCat Mexico 2009 catastrophe bond are to remain the same despite a change to the way AIR Worldwide is modelling the hurricane risk associated with it.
Since the preliminary ratings were first assigned AIR Worldwide has corrected its modelling by adding a second step which identifies two further historical hurricane events (Madeline in 1976 and Ivan in 2004). Both these newly added storms would have caused the class C and D notes to attach under this transaction, thus the modelled probability of attachment has increased slightly. S&P haven’t found this change enough to warrant changing the ratings on the transaction.
